PURPOSE: The Le Fort II midfacial advancement appears to be an effective surgical method for the treatment of severe midfacial-nose hypoplasia with a skeletal class III malocclusion, which is usually combined with syndromic midfacial anomalies. However, the conventional surgical method requires the coronal approach, including a coronal incision, together with other surgical approaches, such as an intraoral incision. Therefore, surgeons often hesitate to propose this type of osteotomy, even for patients who develop severe nonsyndromic midfacial-nose hypoplasia. This report presents a new surgical approach for performing a safe Le Fort II osteotomy for nasomaxillary, midfacial corrective advancement via a solely intraoral approach.
MATERIALS AND METHODS: Surgery was performed with endoscopically assisted piezoelectric surgery. The osteotomized nasomaxillary Le Fort II segment was successfully protracted without aggressive down-fracture procedures with the sole intraoperative use of a rigid external distraction (RED) system, followed by internal rigid fixation, and the subsequent removal of the RED system. Seven patients (all patients were nonsyndromic, but 2 had cleft lip and palate, and an average age of 19.9 years) were included in this study.
RESULTS: The degrees of midfacial advancement at the base of nasal bone (the top edge of the modified Le Fort II segment) that was osteotomized and at maxillary point A was 8.3 mm (range 5.8 mm to 10.5mm) and 8.5 mm (range 5.9 mm to 9.8 mm), respectively.
CONCLUSION: This new method less invasively facilitates safe, secure, and ideal nasomaxillary midfacial protraction to yield a satisfactory resultant facial profile and favorable occlusion in patients with severe midfacial-nose hypoplasia and skeletal class III malocclusions.
